I would think the metatheological fact you want to be realist about is something like “there is a fact of the matter about whether the God of Christianity exists.” “The God of Christianity doesn’t exist” strikes me as an object-level theological fact.
The metaethical nihilist usually makes the cut at claims that entail the existence of normative properties. That is, “pleasure is not good” is not a normative fact, as long as it isn’t read to entail that pleasure is bad. “Pleasure is not good” does not by itself entail the existence of any normative property.
